- [Instructor] There are a number of basic factors
that will affect the tolerance limits of your shop.
First and foremost, any given piece of machinery,
like a lathe, a mill, or a 3D printer,
will have a design tolerance specified by its manufacturer.
These tolerances are listed in the specifications,
or documentation for that product.
This design tolerance
will typically be the primary tolerance limit for your shop.
Once you've purchased a machine,
the setup, tuning, and maintenance of that machine,
can impact how likely you are
to be able to maintain the factory tolerance.
Finally, it's important to be able
to check that parts are machined
to the proper tolerance specifications.
In order to verify the dimensions of a part,
you need measuring tools that have a greater precision
then there tolerance being evaluated.
